Abstract
Different weft threads are drawn off of different supply spools and are inserted through a first and a second jet arrangement in accordance with a predetermined insertion sequence. In the process, the fluid supply pressure for at least a portion of the second jet arrangement is selected at different values for the different types of weft thread. This pressure is changed synchronously with the weft insertion sequence. In this way, different weft thread types may be inserted in combinations not heretofore possible without leading to problems, e.g., operating problems or weaving faults. These problems are avoided since the weft threads of each type are transported optimally and gently, and are held taut without damaging the threads.
